Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed. October 3].y 1907. Serial No. 400,059.

To all whom t may concern:

Be it known that I, BnxJAwix iV. Brunn', i

a citizen of the IInited States, residing at Monticello, in the county of Jefferson and State of Florida, have invented a new and useful Axle, of which the following is a specification.

The invention relates to in'iprovemeuts in axles.

rIhe object of the present invention is to improve the construction of that class ot' axles, which are equipped with skeins, and

to increase their strength and durability and to lessen the co-t of ctmstruction, and

to provide means for cushioning` the skein to prevent the same from being injured.

iliith these and other objects in view, the 3 invention consists in the construction and no\ el combination ot parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the forni, proportion,

size and minor details of construction,l

within the scope of the claims, may be resorted to without departing from the spirit t or sacrificing any invention,

In the drawing:-Figure l is a longitudinal sectional view partly in elevation, showing an axle, constructed in accordance with this invention. Fig. 2 is a sectional view on the line 2-2 of Fig. l. Fig. 3 is a similar view on the line Sk8 of Fig. l. Eig. fl is a detail perspective view of one ot' the cushioning strips.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

l designates a skein-supporting arni, constructed of suitable material and preferably formed integral with a metallic axle Q, as illustrated in Fig. I of the drawing, but the axle skein 4- and the skein-supporting arm l may be applied to an ordinary wooden axletree if desired. '"he axle, which is recot' the advantages of the .L tangular in cross section, is arranged with its face at an inclination to forni a tapered upper portion, which is fitted in a groove 5 of a wooden axle bed (5, whereby it is interlocked with the same. The groove is triangular in cross section to conform to the configuration of the upper half of the axle, and the latter is secured to the axle bed by t means of a clip T, provided with a clip plate i S having a V-shaped intermediate portion tl i to tit the lower half of the axle. The clip i plate is secured to the clip in the usual man I ner by nuts llt). The axle 2 may, however, i be arranged in the usual manner with its upper and lower faces horizontal and its side faces vertical. rI`he axle skein is provided at its inner i end with an integral annular collar ll., i which tits against the adjacent end of the axle bed. rI`he skein-supporti ug arm l, which is rectangular in cross section, tapered l from the collar to its outer end, and it is art ranged with its llat faces set at an inclination. The axle skein, which is constructed of cast metal, has a tapered interior and is provided with interior longitudinal groovesI 112, which receive the longitudinal edges of the skein-supporting arm, whereby the axle skein is interlocked with the arm l and is 1 firmly supported at four points by the same, l as clarly illustrated in Fig. Q of the drawing. By means of the taper of the interior i of the skein and of the skein-supporting arm, the former is wedged on the latter.

The skein is cushioned by means of tapered elastic cushioning strips 13, constructed of wood, or other relatively yieldable material and interposed between the flat faces of the axle and the curved inner face of the circular opening or bore of the axle skein. The elastic cushioning strips, which are adapted to prevent the axle skein from breaking, are substantially segmental in cross section being provided with flat inner faces to fit the axle and curved outer faces to tit the interior of the axle skein. These strips are of a width less than the faces of the arm l and terminate short of the corners thereof to enable the corners to project into the longitudinal grooves of the axle skein.

The axle skein is retained on the supporting arm I by means of a nut 14, which is arranged on the threaded outer portion 15 of a reduced extension 1G of the arm. The reduced extension, which constitutes an integral bolt, passes through a central opening 17 of the outer end 1S of the axle skein, and is projected beyond the saine, as clearly illustrated in Fig. l of the drawing. The outer end of the axle skein is reduced and provided with exterior screw threads 19 to receive an axle nut 20.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent, is

l. ln a device of the class described, the combination with an axle skein, of a polygonal skeinsupporting arm receiving the axle skein and having its corners supporting the saine, and cushioning means interposed between the faces of the supporting arm and the skein.

ln device of the class described, the combination with an axle skein, of a polygonal skein-supporting arm receiving the axle skein and having its corners supporting the saine, and cushioning strips extending along the supporting arm and arranged on the faces thereof and interposed between the same and the axle skein.

combination with an axle skein having a curved inner face, of a polygonal arm provided with flat faces and having its corners receiving and supporting the skein, and elastic cushioning strips interposed between the flat laces of the arm and the axle skein, said cushioning strips being substantially segmental in cross section to [it the skein and the arm.

d. In a device of the class described, the combination of an axle skein having a curved inner face and provided in the said inner curved face with longitudinal grooves extending from one end of the axle skein to e. ln a device of the class described, the

sofi-,eva

the other, and a polygonal supporting arm receiving the axle skein and having corners fitting in the grooves thereof throughout the entire length of the arm, whereby the skein is interlocked with the arm.

ln a device of the class described, the combination of an axle skein having a curved inner face and provided therein with longitudinal grooves, a polygonal supporting arm receiving the axle skein and having corners fitting in the grooves thereof, whereby the skein is interlocked with the arm, and segmental cushioning strips arranged on the flat faces of the arm and interposed between the same and the skein.

G. In a device of the class described, the combination of a tapered polygonal supporting arm having flat faces, and an axle skein provided with a circular bore or opening tapered longitudinally and provided in the curved walls of the bore or opening with longitudinal grooves extending' the entire length of the bore or opening to receive the edges of the arm, said skein being wedged on and interlocked with the arm.

ln testimony, that l claim the foregoing as my own, l have hereto affixed my signature in the presence of two witnesses.
